resolve -t completeness issue

[wisechengyi]

Hi,

I've noticed that when two artifacts with share a set of dependencies, resolve -t will not show one of them.

$ ./coursier resolve -t org.apache.avro:avro:1.7.4
  Result:
└─ org.apache.avro:avro:1.7.4
   ├─ com.thoughtworks.paranamer:paranamer:2.3
   ├─ org.apache.commons:commons-compress:1.4.1
   │  └─ org.tukaani:xz:1.0
   ├─ org.codehaus.jackson:jackson-core-asl:1.8.8
   ├─ org.codehaus.jackson:jackson-mapper-asl:1.8.8
   │  └─ org.codehaus.jackson:jackson-core-asl:1.8.8
   ├─ org.slf4j:slf4j-api:1.6.4
   └─ org.xerial.snappy:snappy-java:1.0.4.1

which includes

   ├─ org.apache.commons:commons-compress:1.4.1
   │  └─ org.tukaani:xz:1.0

but if I do

./coursier resolve -t org.apache.avro:avro:1.7.4 org.apache.commons:commons-compress:1.4.1
 Result:
├─ org.apache.avro:avro:1.7.4
│  ├─ com.thoughtworks.paranamer:paranamer:2.3
│  ├─ org.apache.commons:commons-compress:1.4.1
│  │  └─ org.tukaani:xz:1.0
│  ├─ org.codehaus.jackson:jackson-core-asl:1.8.8
│  ├─ org.codehaus.jackson:jackson-mapper-asl:1.8.8
│  │  └─ org.codehaus.jackson:jackson-core-asl:1.8.8
│  ├─ org.slf4j:slf4j-api:1.6.4
│  └─ org.xerial.snappy:snappy-java:1.0.4.1
└─ org.apache.commons:commons-compress:1.4.1
          // why is there nothing over here?

the root level org.apache.commons:commons-compress:1.4.1 does not have its dependencies printed out.

1. Is that expect?
2. If yes, can I force coursier to print out all transitive dependencies from the roots specified?

Thanks,
Yi

which is also inconsistent with the following result that root will have the transitive dependencies.

$ ./coursier resolve -t -n 12  net.java.dev.jets3t:jets3t:0.9.0   
  Result:
└─ net.java.dev.jets3t:jets3t:0.9.0
   ├─ com.jamesmurty.utils:java-xmlbuilder:0.4
   ├─ commons-codec:commons-codec:1.4
   ├─ commons-logging:commons-logging:1.1.1
   ├─ org.apache.httpcomponents:httpclient:4.1.2 // then i put this as one of the roots to resolve
   │  └─ org.apache.httpcomponents:httpcore:4.1.2
   └─ org.apache.httpcomponents:httpcore:4.1.2

$ ./coursier resolve -t -n 12  net.java.dev.jets3t:jets3t:0.9.0   org.apache.httpcomponents:httpclient:4.1.2
  Result:
├─ net.java.dev.jets3t:jets3t:0.9.0

HI @alexarchambault , I put up a PR #671 for this. It basically will output the complete tree transitively. Given the behavior before was explicitly excluding the jars that have already been printed, was that intended and should I add it behind an option?
